[sustran] Re: Mumbai monorail project looks to reduce CO2 emissions ???

[Walter Hook]

eric,

we are developing these parameters for brt also, and there is also a give
back on co2 from constructoin, though usually its smaller, and if you need
to build the elevated brt (like they are doing in ahmedabad in places) there
is a lot of concrete there also.  its not a brt/mrt thing.  i am trying to
integrate the evaluation criteria to look at mrt and brt and other optoins
using similar methods.  i am in guanzhou for the opening of the bRT here and
one veyr nice feature is its integration with the metro system, maybe the
first time we get nice full integratoin.  the brt is not on a corridor with
mrt in the long term plan, so its additional and not competitive.
